Abstract

Le problème à résoudre dans le cadre de l'invention consiste à fournir un trou d'interconnexion pour envoyer une énergie électrique à une pompe immergée et installée dans une cuve de gaz liquéfiés cryogéniques, comme du GNL et du GPL. Le trou d'interconnexion possède une structure simple et peut rechercher les fuites des gaz et de l'air, à faible coût. Le moyen de résoudre le problème consiste à ce que, dans le trou d'interconnexion (50), une traversée (16) constituée d'un matériau isolant soit insérée dans l'orifice d'insertion de la traversée (14) d'une bride (12) et un conducteur (18) est inséré dans la partie creuse de la traversée. Un intervalle entre la bride et chaque extrémité de l'orifice d'insertion de la traversée et un intervalle entre chaque extrémité de la traversée et le conducteur sont scellés de manière hermétique par des éléments de scellement (20, 22, 24, 26). Un orifice traversant (52) est formé dans la paroi de la traversée et une partie d'espace (54) communiquant avec l'orifice traversant est formée dans la bride. La pression dans l'espace de la bride est détectée par un détecteur de pression (56).
